. Operation &Maintenance Introduction The underground wire locator is designed to allow the user to track low voltage cables used for garden and landscapes automatic watering systems, and also low voltage garden lighting systems. It can also be used to trace other metal cables. The system uses a “transmitter” to send a signal down ths cable being traced or to a solenoid valve that Is being located. A “receiver” Is then used to pick up the signal and follow the cable or locate the coll. A.
F. Measuring Depth Once the path has been determined, mark the ground at a null point along the path. Hold the Receiver antenna at a 45-degrees angle to the ground and move at a right angle away from the path of the wits until anathema null Is found. Mark this point. the distance between the two marks Is the approximate depth of the wire. {fig.01) Receiver Antenna Null Points {Fig.01) Measuring Depth Cable or Pipe 6. Pinpointing Drill Sites Setup the Transmitter as described in (Fig.
H. External Earphones The 3.5mm earphones can be connected fo the Receiver earphone jack to improve efficiency in a noisy environment. {Fig.03) Fig 1. White LED Flash-Light The user can activate the LED flash-light by pressing the ‘Push For Light button. (Fig.04) Flag The only field service required for maintaining proper operation is the periodic replacement of the batteries in the Transmitter and Receiver. Battery Replacement elide off battery compartment cover. 2.Replace the 9V battery. Observe polarity.
